Description

A tourniquet and method of use

Technical Field

The invention relates to the technical field of medical devices, in particular to a tourniquet.

Background technique

In existing medical practice, tourniquets are usually used to temporarily block blood flow in the limbs in order to reduce bleeding during blood collection, intravenous injection or surgery. They are suitable for one-time use in medical institutions for infusion, blood drawing, blood transfusion, and hemostasis during routine treatment and rescue, or for emergency hemostasis in case of limb bleeding or bleeding caused by snake and insect bites in the wild. The tourniquet is wrapped around the injured part, and then the pressure is increased in some way until the tourniquet is tight enough to reduce or stop blood flow. When using a tourniquet to stop bleeding, the binding position needs to be selected at a position where the wound is away from the heart. Generally, the tourniquet should be tied above the injured part, that is, on the side farther from the heart, in order to reduce bleeding. The upper limbs are generally tied at the middle and upper 1/3 of the upper arm, and the lower limbs are tied at the middle and upper 1/3 of the thigh. Traditional tourniquets are usually difficult to apply pressure evenly, which may result in excessive or insufficient local compression. Excessive compression will damage blood vessels and surrounding tissues, while insufficient pressure cannot effectively stop bleeding. In addition, it is often at a fixed pressure value depending on the use of different people, and the effect of use is relatively low.
